PC Specs
I'm getting ready to build my first PC and I was wondering how these specs sound. If I'm missing anything or unsure what to get, please let me know.

MB: ECS K7S5A
Processor: AMD 1700+ or 1800+
Memory: SDRAM for now DDR later since this MB can support either or
Video Card: GEforce2 mx400 (something intermediate, not a very serious gamer)
Sound Card: Soundblaster PCI or Soundblaster Live (please suggest, like good sound quality)
NIC: D-Link card for old system
DVD-Rom: Possibly 16x, but not sure on brand (please suggest)
CD-RW: HP 9510i from old system
Hard Drive: 60GB or 80GB 7200rpm (WD, Maxtor, IBM, not sure which one yet)
Floppy Drive: Doesn't Matter (please suggest)
Modem: 56k something (please suggest)
Power Supply: ? (please suggest)
Case: Case1 or Case2

I think that pretty much covers it, but if I'm missing something please let me know. Thanks for all the help and any suggestions provided.
